When you create new power network structures in your current plant by dragging items from the Reference Electrical Engineer to the Electrical Engineer, there are specific rules that determine how the software creates new items and the electrical associations with the items that already exist in the target plant. When you drag an item to the Electrical Engineer, the software includes that item and all items that are below it in the hierarchy, which together constitute the scope of copied items.
The following rules apply to dragged items:
-
The software assigns names to the items created in the target plant according to the target plant naming conventions.
-
Items that the software creates in the target plant inherit the properties of their source items.
-
If you drag a load to the root (Plant) of the target plant, the software copies the load, but does not associate it with any item in the Electrical Engineer -instead the load appears in the appropriate folder of the Electrical Index.
-
The software copies the electrical relationships that existed among the items in the scope to the target plant. The software creates a new relationship between the dragged item at the top of the hierarchy and the target item. This new relationship follows the rules that apply when dragging items within the Electrical Engineer. For more information, see Rules for Changing Electrical Associations.
-
When copying a network that includes cables, the software uses the source reference cable's SP_ID to identify the reference cable in the target plant. If the software cannot find the reference cable, it uses the cable category, the cable specification, and the cable formation properties to identify the reference cable. If none of these properties can be found, the software creates a new reference cable in the target plant based on the properties of the source cable.
-
Cables that are created in the target plant include the conductor arrangement of the source and all the sizing data. The software copies the reference cables to the Reference Data Explorer in the target plant and associates them with the plant power cables.
-
When the scope includes buses, the software copies their PDBs and PDB-bus associations to the target plant.
-
When the scope includes circuits that have cells, the software copies these cells and their circuit associations to the target plant.
-
When the scope includes circuits that contain internal components, the software copies the circuits and their internal components to the target plant.
-
When the scope includes an auxiliary contact, special rules apply depending on the electrical branch that you want to copy. For details, see Rules for Copying Branches with Auxiliary Contacts.
-
When copying loads or circuits, the software also copies all the signal data associated with these items to the target plant.
-
When copying an item that is associated with a control station, the software copies the pertinent control stations and control station cables to the Electrical Index in the target plant.
-
When copying a load that is associated with a typical schematic, the software copies the relevant typical schematics and typical blocks to the Reference Data Explorer in the target plant.
-
The software does not support the copying of equipment connected in parallel. Therefore, if you copy an electrical branch that is connected in parallel in the Reference Electrical Engineer, these items will not be copied to the Electrical Engineer.
